To all whom t may concern:

Be it known that we, GEORGE H. JENKINS, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, and SAMUEL A. HYEns, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Binders, of which the followlo ing is a specification.

This invention relates to a construction of binding particularly adapted for loose leaf records, etc., and is concerned chiefly with the binding means initially used in its relation to the binding ultimately effected.

Among other objects of this invention, we have sought to eliminate the use of eXtra elements and accessories such as are commonly required when a binding is to be peri formed; to construct the parts so that an efficient and inexpensive binding will result; and to generally reduce the labor, time and cost of effecting a transfer of leaves from temporary to permanent binding covers.

i The invention consists further in numerous other features of construction and combinations of parts, as will more fully hereinafter appear.

[ 3u t Figure 1 is a transverse section through a number of leaves bound between temporary covers, one permanent cover being shown in position;

Fig. 2 is a view similar to Fig. 1, show- Bt' ing the permanent covers and other elements in process of binding; and

Fig. 3 is a perspective view of the volume as permanently bound, without, however, representing any stiifening or reinforcing it@ elements secured to the book back.

As before suggested, this invention is particularly useful in the case of loose leaf books, where the contents are usediirst for current work and later are transferred into permanent form for reference work. The

covers employed for current work are usually carefully constructed, due to the handling and use to which such books are subjected. When a transfer of contents is made to permanent covers in which they are bound,

such covers need not be as carefully nor eX- pensively constructed. It is desirable, however, that the so-called temporary covers be available for further use and that the permanent binding operation shall involve as little expense, time and labor as possible.

It is toattain vsuch ends that the binding construction of the vpresent invention has been devised.

In Fig. l of the drawing we have represented a quantity of leaves 4, arranged between temporary covers 5 and 6, one of the permanent covers 7 also being' shown in position. rllhe means used to retain the leaves and covers in bound relation are here shown as the posts 8, extending through suitable openings in the leaves and covers, one end of each post being formed with a head 9 arranged to be secured to the temporary cover through such means as screws 10. While this form of construction is shown and described, obviously the purposes of our invention would be satisfied with any other equivalent construction.

The construction just described provides a connection between the post and cover 5 which may be conveniently disestablished from the outer side of the cover. The other end l1 of the posts 8 is threaded to receive a compression screw 12, the function and op- @0 eration of which is too manifest to require explanation.

At the time the leaves are assembled between the covers 5 and 6, the permanent cover 7 is also installed in position. When, 35 therefore, a transfer of the leavesA is to be made to permanent covers, the temporary cover 6 is iirst replaced by the second permanent cover 13 and the connection between the post heads 9 and cover 5 is disestablished to permit removal of such cover. Under these circumstances the parts will be related as shown in Fig. 2. The degree of compression desirable for binding purposes may be secured by manipulating the screws 12, after which cords, strings, wire, posts, bolts, or other suitable fastening elements are passed through the leaves and covers to effect a permanent binding of the book.

The holes required for passage of such we fastening elements may be provided in the leaves previous to use or be punched or drilled, or otherwise provided, at the time the binding operation is being eected. When such fastening elements 14C are secured permanently in place, the posts 8 may be removed and be replaced between the temporary covers, to be available for further use.

The invention as herein set forth comu@ prises a form of temporary binder which is seen to function briedy and in an edective manner at the time transfer is made to per-v manent covers. It is to be noted that no parts or elements are required especially to assistV only at the time permanent binding is being performed, but that the elements comF prising the temporary binder serve at such time for such purposes.

lVe claim:

1. In combination With a quantity of stacked leaves, temporary covers adapted to be secured on opposite sides of the leaf stack, a permanent cover arranged adjacent to and inside of one of said temporary covers, removable temporary binding elements arranged to engage with each of said leaves and covers, and to be disengaged therefrom When desired, a Second permanent cover adapted to replace the temporary cover which lies adjacent to the leaf stack, the temporary binding elements being capable prior to removal ofcompressing the leaves between the permanent covers, and permanent binding elements for tying the leaves and permanent covers together, substantially as described.

l2. In combination With a quantity of stacked leaves, temporary covers adapted to be secured on opposite sides of the leaf stack, a permanent cover arranged adjacent to and inside of one of said temporary covers, removable temporary binding elements arranged to engage With each of said rary cover which lies adjacent to the leaf i stack, and to be bound to said leaf stack by means independent of the temporary bind- 111g elements, said binding elements being capable when disengaged from the temporary covers ofY compressing the leaves between the permanant covers, substantially as described. Y

3. In combination with a quantity of stacked leaves, temporary covers adapted to be secured on opposite sides of the leaf stack; a permanent cover arranged adjacent to and inside'of one of said temporary covers, removable temporary binding elements arranged to engage with each of said leaves and covers, and to be disengaged therefrom when desired, and a second'permanent cover adapted to replace the temporary cover which lies adjacent to the leaf stack, the temporary binding elements being .capable prior to removal of compressing the leaves between the permanent covers, substantially as described.
